How to install Vertiv Liebert EXS V-Model UPS

Careful installation is essential to maximize reliability and protection. The Vertiv Liebert EXS V-Model should be placed on a level, vibration-free surface with adequate clearance for cooling and maintenance. Before installation, confirm that the service area meets the electrical, environmental, and safety requirements outlined in the user manual. The following guidelines help ensure a smooth deployment:

Step-by-step guidance:

• Site readiness: Ensure the installation location provides structural support for the unit’s weight, proper ventilation, and access for maintenance. Maintain ambient temperatures within the recommended range and keep the area free of dust and obstructions.
• Electrical connections: Connect the three-phase, four-wire input to the appropriate power source, ensuring correct voltage and phase alignment. Use correctly rated cables and secure all connections to prevent impedance-related issues.
• Load assessment and distribution: Map critical loads to the UPS output and verify that total connected load does not exceed the 20 kW rating. Consider future expansion and implement proper load balancing to optimize performance.
• Cabling and grounding: Route output cables to IT equipment with attention to separation from EMI sources. Ground the UPS per local codes and the manufacturer’s recommendations to ensure safety and performance.
• SNMP and network configuration: Install the SNMP management module if not pre-installed, then configure IP addressing, community strings, and alert thresholds to enable remote monitoring and proactive maintenance.
• Commissioning and testing: Power up the system with a slow ramp, verify alarm indicators, perform a functional test by simulating a power outage, and confirm seamless transfer to an auxiliary power path or battery reserve as designed.
• Documentation and maintenance planning: Record serial numbers, firmware versions, and configuration settings. Establish a preventive maintenance schedule to maximize uptime and extend service life.
